The receiver component converts the optical serial data into an electrical data (RD+ and
RD–). The Signal Detect output (SD) shows whether an optical signal is present.
The transmitter part converts electrical LVPECL compatible serial data (TD+ and TD–)
into optical serial data.
The module has an integrated shutdown function that switches the laser off in the event
of an internal failure.
Reset is only possible if the power is turned off, and then on again. (

The transmitter contains a laser driver circuit that drives the modulation and bias current
of the laser diode. The currents are controlled by a power control circuit to guarantee
constant output power of the laser over temperature and aging. The power control uses
the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a
controlling signal, to prevent the laser power from exceeding the operating limits.
